Distributed File Locking for a Network File Share

2. The method of claim 1, wherein the addressable node is selected, based on one or more load balancing criteria and from among the plurality of addressable nodes, to process the request for write access to the file.

3. The method of claim 1, wherein storing the file locking information at the file share comprises storing the file locking information in a file share directory containing the file.

5. The method of claim 1, further comprising storing, at the file share and for each addressable node of the plurality of addressable nodes, corresponding file locking information that is respectively associated with the addressable node, wherein the corresponding file locking information indicates one or more file handles held at the addressable node.

8. The method of claim 1, wherein the second addressable node is different than the addressable node that released the file handle.

10. The system of claim 9, wherein the instructions, when executed by the one or more processors of the system, further cause the system to select, based on one or more load balancing criteria and from among the plurality of addressable nodes, one of the plurality of addressable nodes to process the request for write access to the file.

11. The system of claim 9, wherein the file share stores the file locking information in a file share directory containing the file.

12. The system of claim 9, wherein the file share stores the file locking information in a lock file.

13. The system of claim 9 wherein the file share stores, for each addressable node of the plurality of addressable nodes, corresponding file locking information that is respectively associated with the addressable node, and wherein the corresponding file locking information indicates one or more file handles held at the addressable node.

15. The system of claim 14, wherein the instructions, when executed by the one or more processors of the system, further cause the system to cause another addressable node of the plurality of addressable nodes to provide, to the addressable node that holds the file handle, a request to release the file handle.

16. The system of claim 9, wherein the second addressable node is different than the addressable node that released the file handle.

18. The method of claim 17, wherein the first file locking information indicates a name of the file, the file handle for the file, and an address of the first addressable node that holds the file handle.
